This target adds support for the Allwinner D1 RISC-V based SoCs.
- RISC-V single-core T-Head C906 (RV64GCV)
- Tensilica HiFi4 DSP
- DDR2/DDR3 support
- 10/100/1000M ethernet
- usual peripherals like USB2, SPI, I2C, PWM, etc.
Four boards are supported:
- Dongshan Nezha STU
- 512Mb RAM
- ethernet
- LicheePi RV Dock
- 512Mb RAM
- wireless-only (RTL8723DS)
- MangoPi MQ-Pro
- 512Mb RAM
- there are pads available for an SPI flash
- wireless-only (RTL8723DS)
- Nezha D1
- 512Mb/1Gb/2Gb RAM
- 256Mb NAND flash
- ethernet, wireless
Installation:
Standard SD-card installation via dd-ing the generated image to
an SD-card of at least 256Mb.

Subject: [PATCH 069/117] ASoC: sun4i-spdif: Simplify code around optional
|
|
resets
|
|
|
|
The driver does not need to care about which variants have a reset;
|
|
the devicetree binding already enforces that the necessary resources are
|
|
provided. Simplify the logic by always calling the optional getter,
|
|
which will return NULL if no reset reference is found.
|
|
|
|
Also clean up the error handling, which should not print a misleading
|
|
error in the EPROBE_DEFER case.
